To provide a method for setting an operation condition of a press line by which a production cycle is improved.

The method for setting the operation condition of the press line includes: a conveyance route setting step (S4) of setting a conveyance route so as to minimize a clearance between a workpiece and a lower die; a phase difference setting step (S7) of setting a phase difference between conveying operations of respective conveyance machines so as to minimize a clearance between a workpiece to be taken-out and a workpiece to be taken-in; and a press-conveyance phase difference setting step (S11) that sets a phase difference between a pressing operation and a conveyance operation in accordance with the conveying route set for each conveyance machine, the phase difference between the conveyance machines, a line SPM, and a press SPM.
